SURGE-TANK.

Application ined 'June e, 192e.

To @ZZ w from t may concern.

Be it known that l, noHILLns A. BA1-:- roN, a citizen of the United States residing' at Glendale, county ot' Los ngeles, and State ot California, have invented a new and useful Surge-Tank, oit' which the tollowing is a specilication.

My invention relates to the art of pumping and is particularly applicable to the art ci pumping wat-er by means of what are commonly called deep well pumps. These pumps usually consist or two 0r three buckets situated near the bottom ot the well and reciprocated in a suitable barrel by means ot pump rods which extend downV through the well. EL though a great deal ot ingenuity has been exercised in devising mechanical motions for giving a constant flow of water 'from such pumps, n verthcless in all commercial forms the buckets must run at a somewhat variable speed and hence the velocity or' the water is variable. l Moreover, the mechanical motions which have been devised in the attempt to give a uniform piston speed are quite complicated and likely to get out of order and are therefore not as satisfactory from a mechanical point of view as a plain crank motion pump in .vhich Vthis variable velocity of the water is very marked.

rlhe principal object ot my invention isv to provide an equalizing device so that the water will have a uniform speed in the line into which the pump delivers quite regardless ot variations in the piston speed of the pump so that the efficiency of pumps having fairly uniform piston speed may be slightly increased and so that crank motion pumps which are otherwise quite inefficient but which are otherwise mechanically satisfac-v tory may be used with an etliciency which is puactically equal to the more expensive unitorni motion pumps.

Referring to the drawings which are for illustrative purposes only,

Figure 1 is a diagram ot a typical installation ot my invention.

Fig. 2 -is an elevation on a somewhat larger scale. this view being broken away and partly shown in section to better illustrate the internal structure.

Fig. 3 is a section on a plane represented by the line 3-3 of Fig. 2.

In the apparatus illustrated in the drawings, 11 is a deep well pump which may be of any standard form, 12 is the surge tank,

13 is the outgoing line, 111 is a compressed air reservoir and 15 is a compressor therefor. rlhe water is pumped -from a well 16 by the pump 11 and delivered at a variable velocity through the pipe 17 into the surge chamber 1 2 where this variable velocity is compensated for, so that the water is delivered to the line 13 at a constant velocity.

The surge tank illustrated in Figs. 2 and 3 (onsists ot a cylindrical shell 2O having a tight top 21 anda tight bottom 22. The inlet pipe 1T delivers the water into the tank near its center and at its periphery in a tangential direction as shown in Fig. 3. The velocity oi the water is dissipated in maintaining' a lwhirling motion around the shell 20. plate 25 is supported ou straps 2G lilling the center of the tank and providing an opening 27 therearound through which the water passes downwardly to the outlet pipe 13. The upper portion ot the tank 23 is kept full of compressed air which is delivered through a pipe 30 into an auxiliary chamber 31 having an air inlet 32 and a water inlet 33 communicating through the walls of the shell 2O with the surge tank proper. side of the auxiliary tank 31 by which the level of the water in the surge tank may be observed. A iioat 4G is provided in the auxiliary tank 317 this lloat operating a valve 41-1 through a rod e2. rlChe valve l1 which may be of any standard construction is so formed that it opens when the float falls and closes when the float rises. A gage 43 is provided in the top ot the auxiliary chamber 31 for observing the pressure of the air. rlfhe tank 14 is provided with some sort of a standard governor, not shown7 so that the air pressure is maintained constant therein within very @lose limits. The water delivered to the pipe 17 at a variable velocit);7 wastes this velocity in a rotary movement, the supply ot water in the surge tank increasing slightly as this velocity increases and decreasing at the lower velocities. As the air pressure in the space 28 is constant7 the pressure ot the water delivered to the pipe 13 is also constant in spite of possible wide variations in the velocity and pressure of the water delivered through the pipe 17. My invention resides particularly in the conceptions of delivering the water into the surge chamber in such a manner that its velocity is broken up and not communicated in any manner to the outlet pipe 13.

A water 0'lass 34 is provided in the,

I claim as my invention:

l. In combination, a pump, a line ed by said pump, walls forming a chamber between said line and said pump, means Jor maintaining a body 0; air under pressure in said chamber, an outlet pipe for withdrawing liquid from said chamber, and an inlet pipe discharging into saidV chamber in such a manner that the velocity of the liquid is destroyed before it enters said outlet pipe.

2. In combination, a pump, a line fed by said pump, walls forming a chamber between said line and said p ump, a float actup tween said line and said pump, means fork maintaining a body of. air under pressure in vsaid chamber, an outlet pipe for withdraw-V ing liquid from said chamber, and an inlet pipe discharging tangentially into said chamber.
